Question

Add three methods to the Student class that compare twoStudent objects. One method should test for equality. A second method should test for less than. The third method should test for greater than or equal to. In each case, the method returns the result of the comparison of the two students’ names. Include a main function that tests all of the comparison operators.

Current code is below:
"""
File: student.py
Resources to manage a student's name and test scores.
"""
class Student(object):
"""Represents a student."""
def __init__(self, name, number):
"""All scores are initially 0."""
self.name = name
self.scores = []
for count in range(number):
self.scores.append(0)
def getName(self):
"""Returns the student's name."""
return self.name

def setScore(self, i, score):
"""Resets the ith score, counting from 1."""
self.scores[i - 1] = score
def getScore(self, i):
"""Returns the ith score, counting from 1."""
return self.scores[i - 1]

def getAverage(self):
"""Returns the average score."""
return sum(self.scores) / len(self._scores)

def getHighScore(self):
"""Returns the highest score."""
return max(self.scores)

def __str__(self):
"""Returns the string representation of the student."""
return "Name: " + self.name + "\\Scores: " + \
" ".join(map(str, self.scores))

# Write method definitions here
def main():
"""A simple test."""
student = Student("Ken", 5)
print(student)
for i in range(1, 6):
student.setScore(i, 100)
print(student)
if __name__ == "__main__":
main()

Answer 1

To compare two Student objects based on their names, we need to add three methods: '__eq__' for equality, '__lt__' for less than, and '__ge__' for greater than or equal to. The main function will create instances of Student and use these methods to compare them. These methods enable the use of comparison operators on the Student class instances based on the name attribute.

Step-by-step explanation:

To add comparison methods to the Student class, we need to define three special methods: __eq__ for equality, __lt__ for less than, and __ge__ for greater than or equal to. These methods will enable us to use comparison operators on Student objects. The comparison will be made based on the students' names.

Here are the methods we need to add to our Student class:

• __eq__(self, other): Returns True if self.name is equal to other.name, False otherwise.
• __lt__(self, other): Returns True if self.name is less than other.name, False otherwise.
• __ge__(self, other): Returns True if self.name is greater than or equal to other.name, False otherwise.

To test these comparison operators, we can add a main function that creates two Student instances and checks equality, less than, and greater than or equal conditions.

Here is the enhanced Student class with the new methods included:

class Student(object):
# Existing methods...

def __eq__(self, other):
return self.name == other.name

def __lt__(self, other):
return self.name < other.name

def __ge__(self, other):
return self.name >= other.name

# Main function for testing...

We can then invoke these methods in the main function to demonstrate their functionality.

Step-by-step explanation:

class Student(object):

def __init__(self, name, number):

self.name = name

self.scores = []

for count in range(number):

self.scores.append(0)

def getName(self):

return self.name

def setScore(self, i, score):

self.scores[i - 1] = score

def getScore(self, i):

return self.scores[i - 1]

def getAverage(self):

return sum(self.scores) / len(self._scores)

def getHighScore(self):

return max(self.scores)

def __eq__(self,student):

return self.name == student.name

def __ge__(self,student):

return self.name == student.name or self.name>student.name

def __lt__(self,student):

return self.name<student.name

def __str__(self):

return "Name: " + self.name + "\\Scores: " + \

" ".join(map(str, self.scores))

def main():

student = Student("Ken", 5)

print(student)

for i in range(1, 6):

student.setScore(i, 100)

print(student)

print("\\Second student")

student2 = Student("Ken", 5)

print(student2)

print("\\Third student")

student3 = Student("Amit", 5)

print(student3)

print("\\Checking equal student1 and student 2")

print(student.__eq__(student2))

print("\\Checking equal student1 and student 3")

print(student.__eq__(student3))

print("\\Checking greater than equal student1 and student 3")

print(student.__ge__(student3))

print("\\Checking less than student1 and student 3")

print(student.__lt__(student3))

if __name__ == "__main__":

main()
